[c-nsp] Cisco Multilink PPP

[Troy Beisigl]

Hi,

 

We are having a problem with Multilink PPP on a 7507 RSP 8 with 4 VIP2-50s.
The RSP is running 256M and the VIPS are running 128M each. We are running
dCEF due to VoIP QoS needs and have 8 multilink interfaces. 7 of these
multilinks are 2 T1s and 1 is 4 T1s is size.

 

Our problem is that we seem to have the VIP in slot 4 crashing. We have
replaced the ram first on this and the problem went away for a week. We
replaced the whole VIP next and still have problems. When it crashes,
multilinks that have T1s on that VIP no longer will pass traffic unless we
do full reboot. 

 

VIP #4 has 7 interfaces that are in multilink bundles. It has 14 interfaces
that are running QoS  (policy map low latency queueing). We currently are
running IOS Version 12.3(15b).

 

Does anyone have any ideas as to what is causing this and what we can do to
solve it?
